2. CT SCAN  CT works well for imaging bone structures.  it's inexpensive, fast and convenient  the skull in the region of the brainstem,, leading to a picture that is very difficult or even impossible to interpret  CT can be more comfortable for patients who are claustrophobic.  contributing to a cancer.  contain iodine. This can cause allergic to iodine MRI  surgical clips, metallic fragments, cardiac monitors or pacemakers cannot receive an MRI  An MRI can take about 45 minutes to complete, whereas a CT scan may only take 5 to 10 minutes.  MRI uses a magnetic field to do the same and has no known side effects related to radiation exposure.  MRI has much higher detail for soft tissue structures.  MRI offers the ability to change the imaging plane without moving the patient.

3. CT SCAN  INTRA CRANIAL HEMMOREHAGE ? equally  detecting acute hemorrhage and problems in bone, such as fractures.  to quickly rule out a serious problem, such as an intracranial hemorrhage.  CT scan is good at detecting acute hemorrhage  diagnose a muscle or look for tumors, a fracture or a blood clot  CT allows accurate detection of calcification and metal foreign bodies MRI  Acute stroke (hemorrhagic or ischemic)  MRI is best at detecting small or subtle lesions, such as multiple sclerosis plaques, acoustic neuromas, or low-grade astrocytomas  Chronic hemorrhage  metal in their bodies that could be moved around or heated up by the powerful magnetic force  DNA damage associated with MRI, "remains unknown" Seyed Kazem Malakouti, MD

4.  CT displays the inner auditory canals and is superior at visualization of the mastoid air cells.  CT shows organ tear and organ injury quickly and efficiently.  Spinal cord is best seen by MRI for the same reason Seyed Kazem Malakouti, MD
